> Key: MYFACES-1430
> URL: http://issues.apache.org/jira/browse/MYFACES-1430
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 1.1.4
> Environment: myFacesCore 1.1.4
> tomahawk 1.1.3
> Tomcat 5.5.17
> jdk 1.5.0.7
> Reporter: Michael Heinen
> Priority: Critical
> Fix For: 1.1.5-SNAPSHOT
>
> Attachments: ddTest.war

>
> After updating myFacesCore to 1.1.4 a selectOneMenu with a binding is not
> working anymore.
> The used version of tomahawk is 1.1.3.
> The entries of the select one menu are cleared after clicking an immediate
> link.
> The BackingBean BBController has session scope.
> When I go back to myFacesCore 1.1.3 everything works fine!!!
> I attached a small demo webApp that everybody can reconstruct this behaviour.

> JSP snippet:
> <f:view>
> <h:form id="myform">
> <h:panelGroup>
> <h:outputText value="MyDropdown" style="padding-right:10px;"/>
> <h:selectOneMenu id="lastSearch"
> binding="#{BBController.savedSearchesMenu}"/>
> </h:panelGroup>
> <h:outputText value="<br/><br/>" escape="false"/>
> <h:commandLink actionListener="#{BBController.doImmediate}"
> value="doImmediate" immediate="true"></h:commandLink>
> <h:outputText value="<br/><br/>" escape="false"/>
> <h:commandLink actionListener="#{BBController.doNormal}"
> value="doNormal"></h:commandLink>
> </h:form>

> BBController snippet:

> public UISelectOne getSavedSearchesMenu() {
> System.out.println ("getSavedSearchesMenu called");
> if (this.savedSearchesMenu==null){
> this.populateSavedSearchesMenu();
> }
> return this.savedSearchesMenu;
> }
>
> public void setSavedSearchesMenu(UISelectOne savedSearchesMenu) {
> System.out.println ("*** setSavedSearchesMenu called");
> this.savedSearchesMenu = savedSearchesMenu;
> }
>
> private SelectItem[] populateSavedSearchesMenu(){
> SelectItem[] selectItems = new SelectItem[5];
> for (int i=0; i<5; i++) {
> selectItems[i] = new SelectItem(i+" testItem");
> }
> this.savedSearchesMenu = new HtmlSelectOneMenu();
> //add an emtpy Select Item
> UISelectItem uiItem = new UISelectItem();

> Output after clicking the immedaite link
> with 1.1.3:
> *** setSavedSearchesMenu called
> doImmediate called
> getSavedSearchesMenu called
> with 1.1.4:
> *** setSavedSearchesMenu called
> doImmediate called
> getSavedSearchesMenu called
> *** setSavedSearchesMenu called
> The obvious difference is the 2.nd call of the setter.
> The parameter savedSearchesMenu (of type HtmlSelectOneMenu) is not
> initialized anymore.
> All attributes are null or false except _valid which is true.
